Abstract (en)

[origin: EP2206925A1] In a rotary compressor (1), a piston (40) is accommodated in a cylinder chamber (60, 65) so as to be eccentric to a cylinder (35), and the cylinder chamber (60, 65) is divided into an outer cylinder chamber (60) and an inner cylinder chamber (65). A blade (45) divides the cylinder chambers (60, 65) into high-pressure chambers (61, 66) and low-pressure chambers (62, 67). Heights (H1, H2) of the outer cylinder chamber (60) and of the inner cylinder chamber (65) in a direction of rotational axis are different from each other.
